Mineral Rights
Oil and gas have been produced in Zavala County since 1937
Zavala County has an oil and gas production history going back to 1937, which matters if you are buying land and want to know what is underground.
The Texas State Historical Association records that Zavala County had produced more than 46 million barrels of oil by 2004. Oil production here started in 1937. When you buy rural land, mineral rights may or may not be included — they can be owned separately from the surface.
The Texas Railroad Commission (RRC) regulates oil and gas in the state. You can search RRC records to find active or plugged wells near any property in the county. This matters for understanding what activity may be on or near land you are considering.
